Both of subtask A&B are to select one among several choices. Thus we implement two of the same model for subtaskA&B. In a nutshell, our model is RoBERTa (A Robustly Optimized BERT Pretraining Approach)[1]} since it has been found that large-scale pre-trained contextualized representation masters a certain degree of commonsense knowledge [2]}. This is also supported by our experimental results.
